Shipping Fast with Contentstack Launch and Edge Delivery

A headless CMS gives you clean content APIs, but you still have to host and serve the front end somewhere. Contentstack Launch is the platform that closes that gap — a hosting and edge delivery layer built to sit directly on top of your Contentstack content, so the CMS and the front end are one connected system rather than two tools you glue together. Here is how it fits into a modern delivery stack.

Why a First-Party Hosting Layer Matters

You can absolutely host a Contentstack front end anywhere. But a first-party platform removes friction: the deploy pipeline already knows about your stack, preview environments are wired to content, and cache invalidation can be tied to publish events. Fewer moving parts means fewer 2 am incidents.

Git-Based Deploys

Launch follows the model every front-end engineer already knows: connect a Git repository, and every push builds and deploys. The mental model:

• Production branch deploys to your live domain
• Feature branches get their own preview URLs automatically
• Every commit is a deployment you can roll back to

git push origin main        -> builds and deploys to production
git push origin feature/x   -> builds a unique preview URL

This makes content and code review symmetrical — a reviewer opens the preview URL and sees the real thing before it ships.

Edge Delivery and Why It Is Fast

Launch serves your built site from a global edge network, so a visitor in Singapore and a visitor in London both hit a nearby node rather than a single origin. For a content site this matters enormously — most of your pages are cacheable, and serving them from the edge turns a 400 ms origin round trip into a 30 ms edge hit.

Edge Functions for Dynamic Logic

Static delivery is fast but sometimes you need logic at request time — geolocation redirects, A/B splits, auth checks, or setting headers. Launch supports edge functions that run at the edge before the response is served:

export default function handler(request) {
  const country = request.headers.get('x-country');
  if (country === 'IN') return Response.redirect('/in', 302);
  return; // continue to the normal page
}

Because this runs at the edge, the personalisation happens without a slow trip back to a central server.

Tie Cache Invalidation to Publishing

The performance win of edge caching comes with one responsibility: when content changes, the cache must know. Wire your publish events so that publishing an entry purges the affected pages. Done right, editors publish and see the change globally within seconds, while every other request still serves from cache.

A Sensible Delivery Checklist

The best content delivery is invisible: editors publish, and the world sees it instantly, everywhere, without anyone thinking about servers.
